Abstract

The invention discloses an LNG gas turbine and a starting system thereof. A combustion chamber, a turbine and a gas compressor are included. The gas compressor is in drive connection with the turbine. The combustion chamber comprises a combustion chamber inlet and a combustion chamber outlet. The turbine comprises a turbine inlet and a turbine outlet. The turbine inlet communicates with the combustion chamber outlet. The gas compressor comprises a gas compressor inlet and a gas compressor outlet. The gas compressor inlet is used for receiving air. The gas compressor outlet communicates with the combustion chamber inlet. The LNG gas turbine further comprises a natural gas conveying channel for conveying natural gas into the combustion chamber. The LNG gas turbine further comprises a natural gas turbine. The natural gas turbine communicates with the natural gas conveying channel, and therefore gaseous natural gas in the natural gas conveying channel acts in the natural gas turbine and then leads to the combustion chamber. The natural gas turbine is connected with the gas compressor, and therefore the natural gas turbine drives the gas compressor to rotate when rotating in the acting process of the natural gas.

Description

Technical field [0001] The invention relates to a starting system of a gas turbine, in particular to an LNG gas turbine and a starting system thereof. Background technique [0002] At present, most gas turbines are started by electric motors, hydraulic pumps, or compressed air. The auxiliary equipment required by these start-up methods all need to consume more useful work. LNG is environmentally friendly and clean, and the price is low. For LNG-burning gas turbines, not using the huge cold energy contained in LNG itself is a great waste. Summary of the invention [0003] In view of this, the present invention proposes an LNG gas turbine startup system that can improve the startup mode of the gas turbine. [0004] The invention also provides an LNG gas turbine which can improve the starting mode of the gas turbine. [0005] An LNG gas turbine includes a combustion chamber, a turbine, and a compressor, the compressor is drivingly connected to the turbine, the combustion chamber incl...
